State v. Bowen, 481 P.3d 370

Trooper stopped Bowen for a traffic violation on Highway 140 (Jan. 2016). Upon approach, the trooper smelled an “obvious” odor of marijuana.
Bowen was driving a rental car from Grants Pass (a city the trooper considered a marijuana source) to Denver; trooper knew Colorado was a market for Oregon marijuana and that people sometimes use rental cars to transport it.
Bowen showed minor nervousness but did not appear impaired. The trooper (based on those facts and his training) extended the stop to question Bowen about marijuana.
During the extended questioning Bowen admitted he was transporting about 15 pounds of marijuana; officers seized ~17 pounds and charged him with unlawful delivery and possession over 32 ounces.
Bowen moved to suppress evidence as the product of an unlawfully extended stop; the trial court denied suppression finding reasonable suspicion of unlawful delivery.
The Court of Appeals reversed: objectively the trooper’s articulated facts (primarily an unspecified odor of marijuana plus travel/rental-car context) did not supply reasonable suspicion to extend the stop under Article I, section 9 of the Oregon Constitution.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether the trooper had reasonable suspicion to extend/expand the traffic stop to investigate unlawful delivery of marijuana	Odor of marijuana on approach, travel from a source city to Colorado in a rental car, nervousness, and officer experience gave rise to reasonable suspicion of delivery	Odor alone and nonspecific travel/rental-car facts are insufficient; facts obtained during the extended stop cannot justify the extension	Reversed: objective facts were insufficient; extension violated Art I, §9 because the trooper lacked reasonable suspicion of unlawful delivery
Whether an odor of marijuana, standing alone, is sufficient post-legalization to support reasonable suspicion of unlawful delivery	Odor can indicate presence of marijuana and, with context, support suspicion of trafficking	Due to legalization and lawful possession/delivery limits, odor alone, without strength, source, or other specifics, is insufficient to infer unlawful delivery	Court emphasized legalization reduces the weight of odor; odor may contribute but is not per se sufficient—here it failed to provide reasonable suspicion
